Hi Falko, I regularly work with OpenJ9 and encountered such issues. Sometimes it is a coding error which does not lead to an error in Hotspot, sometimes it is a J9 problem (e.g. JIT problems, class loading, etc.).
If you want to dig in, there are a few things you can try: The JVM option -verbose:class will show every class loaded. You could also enable verbose GC to see if the class got somehow unloaded [1]. If it was loaded and is then unloaded early, you can try to use -Xnoclassgc [2] and see if that helps. If it does, please write down the exact commit ID you are working with and create a github issue [3] at OpenJ9. Please note that those options might not work on a hotspot VM. Let us know if you found anything! - Ben [1]: https://www.eclipse.org/openj9/docs/xverbosegclog/ [2]: https://www.eclipse.org/openj9/docs/xclassgc/ [3]: https://github.com/eclipse/openj9/issues/new/choose Am So., 28.
